Next to the other running costs for any Porsche that's pretty cheap to look after you engine properly.

Suggestion
I have also recently started using Millers Nanotech which is reputed to reduce friction, which can't be a bad thing given the bore scoring issues.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

As above. I change mine every year.
I have also recently started using Millers Nanotech which is reputed to reduce friction, which can't be a bad thing given the bore scoring issues.
I've been pricing up OPC oil change (supplying the oil myself) as its almost a year since a major service on my 997 turbo.
OPC said its two years but I've always changed it more often. I'm only likely to have covered 2.5-3k miles in the year, and they said its not needed.
Perhaps I'm over servicing and modern engines don't need it?
It's about £120 all in if you supply your own oil. Next to the other running costs for any Porsche that's pretty cheap to look after you engine properly.
I've seen oil analysis results from other cars (albeit older ones) that shows even modern oils start to degrade surprisingly quickly. I wouldn't want to be using the same batch after more than a year or 6000 miles.

Are you saying this helps reduce scoring?

Hartech are of the opinion that it could contribute towards avoiding bore scoring.
From what I can gather it coats surfaces with a film of some sort (sorry for the lack of technical knowledge) that helps to reduce friction and therefore could assist in preventing the dreaded bore scoring.
Any little bit that can help is good enough for me.
